Listeria monocytogenes, Yersinia enterocolitica, and Salmonella in dairy plant environments.

In order to determine the presence of the three environmental pathogens in dairy plants, six milk and four ice cream plants in a three state area were sampled. A total of 353 environmental samples were taken over three replications. Bacterial counts were performed on the environmental samples for chi-square analysis. Salmonella spp. were not isolated from any of the environmental samples. Yersinia enterocolitica was isolated from 6.8% of the environmental samples. Listeria monocytogenes was isolated from 6.5% of the environmental samples. Listeria spp. other than L. monocytogenes were isolated from 9.3% of the environmental samples. The presence of Y. enterocolitica was significantly related to high bacterial counts for six microbiological tests. The presence of L. monocytogenes was not related to high bacterial counts.

Helping employees and families cope with breast cancer treatment.

With respect to a lump in the breast, all findings can be considered significant until necessary evaluation is completed. Persons who have cancer often attribute all symptomatology to the disease; therefore, the nurse needs to allay fears about commonly occurring illnesses, while staying attuned to indications of metastasis. Keeping up-to-date with a rapidly changing field will be a challenge to nurses in the position to counsel and to have a positive effect on the lives of millions of women with or at risk for breast cancer. The occupational health nurse is in a strategic position to encourage prevention and surveillance, as well as to counsel employees during diagnosis, treatment, and rehabilitation.

Clinical experience with ciprofloxacin: analysis of a multi-practice study.

In a multi-practice study of 113 patients treated with ciprofloxacin (mean daily dosage, 995 mg per day; mean duration of treatment, 9.6 days) for a variety of infections, 14 were microbiologically proven. Of these, bacteriologic cure and/or improvement resulted in 92.9% of cases. For all 113 infections, clinical cure and/or improvement resulted in 97.1% of cases. A total of 17 infections were classified as chronic. Therapy with ciprofloxacin was discontinued in three (2.6%) of 113 patients because of adverse effects. Overall, there were 5/113 (4.4%) adverse reactions (ADRs). Only one ADR was related definitely to ciprofloxacin therapy. Two ADRs were definitely not related; in two the relationship was uncertain. Two patients of the five (40%) elected to continue ciprofloxacin therapy despite mild side effects.

Where have all the nurses gone--and why?

Although the nurse supply is at record number; hospitals everywhere are having trouble filling vacant positions. Is the current shortage one of numbers, or is it the result of nurses being unwilling to work under present conditions?

Characterization of a heat-stable protease of Pseudomonas fluorescens P26.

A heat-stable, extracellular proteolytic enzyme was isolated from Pseudomonas fluorescens P26. Brain heart infusion broth (Fisher Scientific Co.), pH 7.5, and incubation at 21 C provided the optimal conditions for bacterial growth for enzyme production. The organism had a D value of 2.6 min at 62.8 C (145 F). The enzyme, however, was quite heat-stable, requiring 15 hr at 62.8 C, 8 hr at 71.4 C, and 9 min at 121 C for complete inactivation. Milk, whey, and casein each had a protective effect on the enzyme against heat inactivation. Purification was accomplished by growth of organisms in broth, centrifugation, sterilization by filtration, ammonium sulfate precipitation (55% saturation), dialysis (against six changes of water), and protein separation by passage through a Sephadex G-100 column. Ultracentrifugation revealed a single band with a sedimentation coefficient of 1.51 which suggested a molecular weight of approximately 23,000. As little as 0.2 unit of the purified enzyme caused detectable flavor defects during 30 days of storage at 4 C, and the Hull test for liberation of tyrosine compared favorably in sensitivity with the sensory method in milk.
